Re: [bug #22052] scons build error on mac -- May 19, 2014 - 11:02

Hi,

Could you try creating the hello.c file with:

"""
#include<stdio.h>

main() {
    printf("Hello world\n");
}
"""

Then type:

$ gcc -arch ppc hello.c -o hello
$ ./hello

What does this show on your system?  Does the gcc command fail?  This
would be the exact extension of the det_arch() method.

Regards,

Edward
